The present invention relates to an acidic electrolyzer and a method of using the acidic water, and more particularly, does not use an ion exchange resin, and in particular, constitutes a plurality of electrodes having one polarity and applies the same polarity to each other. By applying the same electrode to the electrode having a polarity through the mesh electrode (Mesh Electrode), by increasing the surface area of the electrode of the electrode having a different polarity, while reducing the interval between the electrodes to promote the redox reaction, Rather, the present invention relates to an acidic electrolyzer and a method of using the acidic water, which can electrolytically decompose pure water (RO) or ultrapure water (DI) to obtain a high concentration of acidic reduced or acidic oxidized water.

As in the patent document, an electrolytic cell for generating alkaline reduced water has been filed and registered. In the alkaline reducing water generating electrolytic cell, the area of the cathode electrode in contact with the electrolytic solution is formed larger than the area of the anode electrode in contact with the electrolytic solution, the anode electrode is seated in the anode chamber with the top open, The outlet of the (n-1) th cathode chamber which is continuously disposed on the side of the anode chamber and is formed in the anode chamber to communicate with the inlet of the adjacent cathode chamber, And communicates with the inlet of the chamber. According to this invention, it is possible to change the liquidity without adding the chemical agent.

The generated alkaline reduced water is useful for cleaning surface particles such as semiconductor wafers and photomasks, and since only pure water or pure water is used as raw material water, it has the effect of solving pattern damage and preventing oxidation of the surface. It can be reused at low cost, which can reduce the environmental problems.

However, the following problems arise in the electrolytic cell described in the patent document.

(1) Since power is independently supplied to a plurality of electrodes having the same polarity, there is a difficulty in stabilizing the electrode surface because the potential difference between these electrodes is not constant.

(2) Since the existing electrolytic cell uses pure water (RO) or ultrapure water (DI) as raw water, the conductivity of these raw waters is low, and ion exchange resins have to be used to increase conductivity.

(3) Repeated use of these ion exchange resins through electrolyzers lowers the heat resistance of the resin and constrains its lifetime.

(4) In general, electrolysis takes place at the electrode surface of the cathode and anode. For this reason, the conventional electrolytic cell has the problem that electrolytic efficiency falls in the part which does not directly contact an electrode surface.

(5) Since the electrodes having the same polarity were separately supplied with power to each other, it acted as a factor of instability in extending the electrode surface.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

The acidic water electrolytic cell according to the first embodiment of the present invention, as shown in Figure 1, is installed in the housing 100, the housing 100, the electrolysis is made of a material having a different polarity to supply power for electrolysis Having the same electrode as the first electrode 200 and the second electrode 300, and any one of these electrodes to increase the potential difference to obtain the acidic oxidation or acidic reduced water.

In particular, the acidic water electrolytic cell according to the present invention configures the filling chambers 110a and 110b by using the ion exchange membrane 111 inside the housing 100 so that the electrolyzed ions can be filled in a predetermined space.

In addition, the acidic water electrolytic cell according to the present invention, by connecting the second electrode 300 and the other electrode (third electrode) having the same polarity as one to supply power of the same intensity, these second electrodes The power is supplied to the 300 and the third electrode at the same time to enable the power supply of the same potential difference to these electrodes to stably extend the surface electrode.

Hereinafter, this configuration will be described in more detail as follows.

The housing 100 is an electrolyzer body for causing electrolysis by receiving a predetermined amount of raw water therein.

The housing 100 is formed in a hollow hollow shape, and is provided with an ion exchange membrane 111 to separate the electrolyzed ions. The ion exchange membrane 111 partitions the inside of the housing 100 into at least two filling chambers 110a and 110b. Although the preferred embodiment of the present invention has been described as being divided into two parts, it is also possible to divide it into more parts. In a preferred embodiment of the present invention, such an ion exchange membrane may use a fluorine-based catch-on exchange membrane (Dupont Nafion 117).

Meanwhile, in each of the filling chambers 110a and 110b, inlets 112a and 113a for receiving raw water for electrolysis and outlets 112b and 113b for discharging the electrolyzed acidic water to the outside are formed.

Here, the filling chambers 110a and 110b are described as being configured in the case of using one ion exchange membrane 111 as described above. However, when " N " pieces are used for the ion exchange membrane 111, (N + 1) filling chambers are formed, and each filling chamber has an outlet and an inlet.

The first electrode 200 is installed in one of the filling chambers 110a. In this case, the first electrode 200 secures a filling space having a predetermined size between the ion exchange membrane 111.

To this end, the first electrode 200 is installed in the filling chamber 110a such that the gap W1 with the ion exchange membrane 111 is 0.1 to 2.0 mm. This is because if the gap W1 becomes wider than this, the electrolysis with the second electrode 300, which will be described later, is reduced, and if the gap W1 is wider than this, the flow of acidic water or raw water may be disturbed.

In the preferred embodiment of the present invention, when the first electrode 200 is mounted on the housing 100 having two or more charging chambers, the first electrode 200 is mounted on the outermost charging chamber.

The second electrode 300 has a different polarity from that of the first electrode 200 and is installed in the other filling chamber 110b to be adjacent to the ion exchange membrane 111.

At this time, when a plurality of charging chambers 110b in which the second electrodes 300 are provided are provided, the second electrodes 300 are installed one by one for each charging chamber.

The third electrode 300 'has the same polarity as the second electrode 300 and is installed in the charging chamber 110b in which the second electrode 300 is installed.

At this time, the third electrode 300 'is spaced apart from the second electrode 300 by a predetermined gap W2. In this case, the gap W2 is formed to be 0.1 to 100.0 mm, and utilized as a space for filling ions therebetween.

Meanwhile, in a preferred embodiment of the present invention, the above-described first to third electrodes 200, 300, and 300 'may use a porous platinum electrode or a mesh platinum electrode.

In addition, in a preferred embodiment of the present invention, the second electrode 300 and the third electrode 300 ′ are connected to each other, for example, in a parallel form so that power can be simultaneously supplied to these electrodes. desirable. This allows power to be simultaneously applied to the second electrode 300 and the third electrode 300 'to which the same polarity is applied, thereby providing a potential difference of the same intensity with respect to the second electrode 300 and the third electrode 300'. It is to provide a stable and evenly extended to the electrode surface to use.

[action]

The operation of the acidic water electrolytic cell according to the present invention having the same structure as that of the first embodiment of the present invention will now be described.

First, raw water is supplied to the housing 100 through the inlet ports 112a and 113a. At this time, the raw water may be supplied through only one of the two inlet ports 112a and 113a.

A positive electrode is applied to the first electrode 200 and a negative electrode is applied to the second electrode 300 and the third electrode 300 '. Thus, as the electrolysis of raw water occurs, OH ⁻ is filled in the filling chamber 110a to which the anode is applied by the ion exchange membrane 111, and H ⁺ is filled in the other filling chamber 110b. In this case, when the second electrode 300 and the third electrode 300 ′ are connected together, power is simultaneously applied to these electrodes.

When OH ^- and H ⁺ are filled in each of the filling chambers 110a and 110b, a current flows due to a potential difference between these ions. In particular, in the case of the filling chamber 110b in which the third electrode 300 'is installed, it is considered that H ⁺ is converted to H or H ₂ due to the increase of the negative (-) ion.

This high potential difference due to the filling of ions can be useful for electrolysis of pure water (RO) or ultrapure water (DI) with low conductivity as well as tap water.

(1) Influence of hydrogen on the cathode side on the retina of the eye.

Retinal ischemia-reperfusion (IR) damage caused by a temporary increase in intraocular pressure (IOP) is known to cause free radicals and damage nerve cells.

IOP of experimental mice was induced for 60 minutes to induce ischemia. During the ischemia reperfusion period, saline eye drops saturated with hydrogen gas composed of acidic hydrogen water according to the present invention were continuously administered.

As a result, the hydrogen concentration in the vitreous body was immediately vaporized and the IR-induced OH was reduced. Eye drops reduced retinal cell death and oxidative stress indicator-positive cell numbers and inhibited retinal thickness loss due to activation of Muller glia, astrocytes, and microglia .

Eye drops restored retinal thickness by more than 70%.

(3) Measurement of the antioxidant power of the hydrogen water obtained from the cathode side

Four-week-old male ICR mice were acclimated for one week, followed by free feeding of feed and hydrogen water for 15 days, and the control group consumed tap water. Hydrogen water was replaced three times a day to prevent the concentration of hydrogen water. After the end of the sample administration, mice were anesthetized with ether and blood was collected from the heart. The collected blood was separated from the plasma of the anticoagulants.

Plasma total antioxidant activity was measured using a kit for measuring total antioxdant status of Randox Inc. (U. K.). Immobility time was measured during 6 minutes of forced swimming to investigate the effects of stamina enhancement. A circular cylinder (height: 25 cm, diameter: 10 cm) was filled with water of 23-25 ° C. to a depth of 10 cm as shown in FIG. 2. A dead time of 4 minutes before termination was measured. The head was placed on the water and the floating posture was immovable.

After the forced swimming test, mice were anesthetized with ether and blood was collected from the heart. The collected blood was centrifuged at 4 ° C at 3000 rpm for 10 minutes to obtain serum.

Using autoanalyzer (Hitachi 747, Hitachi, Japan), blood urea nitrogen, creatin kinase, lactic dehydrogenase, glucose and total protein total protein) were measured. Measurements were analyzed by Student's t-test and expressed as M ± SEM.

Oxygen is an essential element for organisms in organic respiration, but active oxygen generated when incomplete reduction during energy metabolism destroys and destroys homeostasis of cells by denaturing and destroying macromolecules in cells. Active oxygen is generated by factors such as tobacco and soot, which damages biological components such as proteins, DNA, enzymes, and T-cells, and causes various diseases, and in particular, attacks fatty fatty acids, which are components of biological membranes, to generate lipid peroxide. It is known to cause aging and adult disease.

5-week-old ICR mice were fed with drinking water for 15 days and plasma was separated to measure the total antioxidant status (Table 3).

As a result, the total antioxidant power of the hydrogen water intake group was significantly increased by 18% compared to the control group ingesting tap water (P <0.05). The total antioxidant power of plasma can be considered as a representative value of the antioxidant power in the body, and the increase in the total plasma antioxidant power means that the antioxidant power in the body is increased by the intake of hydrogen water. These results show that hydrogen water can increase the antioxidant power of the living body to protect the living body from various diseases and aging caused by various factors.

Forced swimming tests are used for anti fatigue and endurance tests. Hydrogen water was ingested for 15 days in male ICR mice of 5 weeks of age and then subjected to a forced swimming test to measure immobility time and blood biochemistry (see FIG. 2). The immersion time in the forced swimming test of the mice was significantly reduced by 13% compared to the control group (see Table 4). This indicates that the intake of hydrogen water acted to increase antifatigue and endurance, thereby reducing immobility period.

This is to allow the acidic water to flow smoothly while reducing interference in the exchange between ions flowing in and out through the ion exchange membrane 111.

Since the mesh electrode 114 installed as described above has the same polarity as the first electrode 200 and is the upper pole of the second polarity 300 disposed on the opposite side with respect to the ion exchange membrane 111, a redox reaction is performed between these electrodes. This will happen. At this time, the reaction distance between the mesh electrode 114 and the second electrode 300 is minimized, and in particular, since the mesh electrode 114 is formed in a mesh form, the redox reaction between the electrodes is further promoted. will be.

In addition, although the configuration of the mesh electrode 114 according to the present invention is described as being installed in the ion exchange membrane 111 of the first embodiment, it is apparent to those skilled in the art that the present invention can be applied to other embodiments.

As described above, the present invention configures a plurality of electrodes having one polarity so that power can be supplied at a time, and the other polarity allows power to be supplied using a mesh electrode, thereby reducing the redox reaction. While increasing the area of the electrode is made, the gap between the reaction electrodes is narrowed to further promote the redox reaction to obtain a high concentration of acidic water.
